Cation Exchange Capacity, CEC, by Summation Method
WebCation exchange capacity is usually measured in soil testing labs by one of two methods. The direct method is to replace the normal mixture of cations on the exchange sites with a single cation such as ammonium (NH 4 + ), to replace that exchangeable NH 4 + with another cation, and then to measure the amount of NH 4 + exchanged (which was how ... WebCation Exchange Capacity, CEC, by Summation Method. CEC is determined by the summation of exchangeable Ca, Mg, Na, K, and Al. Base cations are extracted by leaching 3 g air dried soil (1 g for peat) with successive aliquots of 1 M NH 4 OAc, pH 7, to total 60 mL. The concentrations of the base cations in the leachate are determined by ICP-OES ... bpm of antifragile
